Well, Anna was able to remember Olaf because the troll left her "the fun" memory...so she remembered building snowmen, playing in the snow with her sister etc--- she just forgot the magic part (you can see how he adjusts her memory, Olaf is still there.)

You're not missing anything, dude. If I was to describe how Cup Noodle tastes and feels, I would say it is like a styrofoam noodle with a pinch of salt that tastes nothing. If you eat half a dozen of it, you still feel you ate nothing. Maybe that's why they did an add that don't seem to have anything to do with their product. There's nothing on Earth that has something to do with it. Well, maybe styrofoam.
